1. Professional player socks are generally made of Lycra cotton, but the disadvantage is that the price is too high; generally speaking, socks with towel bottoms are the most cost-effective. For socks, there is no real pure cotton socks. Generally, the cotton yarn content of socks is about 60% to 85%. The socks need a certain elasticity, which must be added in the weaving process. Certain elastic fibers, such as Lycra is the best material for the skin. Generally, the whole pair of socks will not be made of Lycra. Many socks are marked as limited to the cuff. Man-made fibers are often used in the toe, heel and cuffs for reinforcement and elasticity, and the two add up to about 15-40%. So what we call pure cotton (whole cotton) socks means that the yarns other than elastic fibers and hanging threads are all cotton.
2. The thickness of socks is not necessarily related to foaming. Wearing two layers of socks is easy to slip, and the feet are naturally more likely to foam.
3. It is best not to use a washing machine to clean the socks, which will make the socks lose their elasticity, and do not soak them for more than 20 minutes.
